The relationships between different reproductive traits and body weight, in relation to nesting site, were studied in European passerines. Body weight explains a significant proportion of the variance in clutch size, egg weight, clutch mass, and incubation period. Whereas clutch size decreases, the other three traits increase with body weight. Even though both clutch mass and clutch size are related to body size, for a given body weight, concealed nesters lay a larger clutch and a greater clutch mass than open-nesters.
